You would have to have a texture prepared for folding over the six sides.
In most cases this would involve a larger power of two texture with the
cross shaped texture inside it. For something like a movie file this would
be impractical. Building this in GEM is the most flexible method.
Ben, I thought you had made an abstraction many years ago to put a texture
on each side of a cube?
